The effect and function of Polyglutamic Acid

Polyglutamic acid (PGA) is a biodegradable polymer made up of repeating units of the amino acid glutamic acid. It has various applications in the fields of cosmetics, medicine, and agriculture. The effect and function of polyglutamic acid can vary depending on its specific use:

1.Skincare and Cosmetics:

Hydration: Polyglutamic acid has strong water-absorbing properties and can hold several times its weight in water, making it an effective hydrating agent in skincare products. It helps to maintain skin moisture and prevent dehydration, leading to smoother and more supple skin.

Moisture Retention: Polyglutamic acid forms a protective film on the skin’s surface, reducing water loss and enhancing the effectiveness of other moisturizing ingredients in skincare products.

Anti-aging: Polyglutamic acid can promote collagen production, which is important for maintaining skin elasticity and reducing the appearance of fine lines and wrinkles.

Brightening: It can also help reduce the appearance of dark spots and pigmentation by improving the overall health and texture of the skin.

2.Wound Healing:

Polyglutamic acid-based wound dressings have been developed to promote faster and more efficient wound healing. The biocompatible nature of Polyglutamic acid allows for better tissue adhesion and reduces inflammation, making it suitable for various types of wounds, including burns and surgical incisions.


Polyglutamic acid can be used in agriculture to improve soil quality and plant growth. It acts as a soil conditioner, enhancing the soil’s water-holding capacity, nutrient retention, and overall structure. This can lead to better crop yields and healthier plants.

4.Drug Delivery:

Polyglutamic acid can be used as a carrier or excipient in pharmaceuticals. It can improve the stability and solubility of certain drugs, making them more effective and easier to administer.

5.Food Industry:

In the food industry, Polyglutamic acid is used as a food additive, primarily as a gelling and thickening agent. It can improve the texture and mouthfeel of various food products.

6.Personal Care Products:

Polyglutamic acid is used in personal care products like shampoos, conditioners, and body lotions to enhance their texture and improve their moisture-retaining properties.

7.Anti-pollution Products:

Polyglutamic acid is often included in anti-pollution skincare products because it can help form a protective barrier on the skin, shielding it from environmental pollutants and impurities.

Overall, polyglutamic acid offers several beneficial effects and functions in a variety of applications, mainly due to its excellent hydrating and film-forming properties, biocompatibility, and biodegradability. Its use in skincare and cosmetics is particularly noteworthy, as it can contribute to healthier, more youthful-looking skin.
